Genes affected
EVC (HGNC:3497): (EvC ciliary complex subunit 1) This gene encodes a protein containing a leucine zipper and a transmembrane domain. This gene has been implicated in both Ellis-van Creveld syndrome (EvC) and Weyers acrodental dysostosis. [provided by RefSeq, Jul 2008]
CRMP1 (HGNC:2365): (collapsin response mediator protein 1) This gene encodes a member of a family of cytosolic phosphoproteins expressed exclusively in the nervous system. The encoded protein is thought to be a part of the semaphorin signal transduction pathway implicated in semaphorin-induced growth cone collapse during neural development. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2008]

This sequence change creates a premature translational stop signal (p.Gly458Glufs*42) in the EVC gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EVC are known to be pathogenic (PMID: 23220543). This variant is present in population databases (rs760607210, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with EVC-related conditions (PMID: 23220543). ClinVar contains an entry for this variant (Variation ID: 555852). For these reasons, this variant has been classified as Pathogenic. -
